Beit known thattl', z'ltromas- GQPLANT, citizen ofthe United.States',residing at Bo'ston',: inthe county. oii Su-fiolkendi State ofMassachusetts, have invented-Ian iImp'rove ment inSole-SewingMachines,of whicl1 the accompanying: drawingaqisfe"specification,

As well known by those skilled in the art, 3 solesewing machines areprovidedwithfa through the work and engages the sewing thread at theoppositeside thereof, andathrough and while still in the work. Theneedleusually asses through the work from;

ously contact with the Work.

'lVith these considerations 1!} View, the object of the presentinvention is tOzPlOVldQ the work is protected from injuriouscontact rtsof the machine, espec ally the looper,--during the sewing operatiOI1T".J

The -invention will best be understood from the following descriptiontaken in connection with the accompanying drawings, which show one formoreinbodiment df the inven! tion which is more'jdefinitely defined as toits scope by the claims.

Figure l is a partial side elcvation of'sufficient portions of a solesewing machine'to disclose the relation of the present inventionthereto, certain parts being broken away and others being shown insection; and Fig. 2 is a front elevation showing sufiicient portions ofthe sole sewing machine to make clear the relation of the inventionthereto,

In the drawings, the frame 1 ma be of E any usual or desiredconstruction suitable for supporting the operating parts of the t'machine, and these also-may be of any usual i SOLE-SEWING MACHINE;

SenerNQesas E or -particulai type Meunte'd Yup-ob the-- machine frame- 1 :is a table wiiieh-aconstitutes; the work? support uponwh-iehthe world-3; rests during; the; sewing" operation.- Disposedabove-the table 2'15 the presserioot-el' which may beef any' usualor desired type:

The handle 8 is employedior lock ing the door ofthe shuttlebox in position.

Also 'nifounted-on the machine 'framel is the maintake-up arnr 9' andtheauxiliary take up 10, said parts being ofusuald orin,and construct onand, tornnng'no part, of the present invention, need no. further descripDisposed below the table on work support Skis-the looper '11 carried bythe actuatmg [ajrna v12 which is itselt' operated n' theusualnitt nierto give to the, loop-3r sub stantially circular. about; the needle 13when the latter has pen'etrated and passed througli the -work toa-=position below the 1 table 2. 1 Front the" construction abovegenerally outlined and Whichis usual inthis class ol machines' and wellunderstood by those skilled in. the art, it will be noted that thelooper11 during its substantially circularniotionaboutthe needle is liable tocontact with the upper of a shoe, as indicated by dotted" lines inFig. 1. Especially is this liable to ha pen, in passing around certainportions 0f"'th e sole, when the shoe upper -is carried somewhat to theleft, in Fig. l. or turned about the work support or table 2 in 'orderthat the line of stitches may take the vdesiatetlmposition withreference te theinseanrwhich secures the ulpperto the insole.

will not be injured, the flexible guard vielding under such contact, aswill be well understood.

The guard 14: is carried by a guard support 15, being secured thereto bymeans of screws or rivets 16, the edge of the guard 14 resting upon ashoulder 17 formed on the V guard support.

T he guard support 15 is pivotally mounted on the machine frame 1 at 18,F ig. 1, and has a tail piece 19 which, when the guard and guard supportare raised into operative position as shown by full lines in Fig. 1, contacts with the frame 1' at 26 which constitutes a stop. in order tomaintain the guard and guard plate in either operative or inoperativeposition, as desired, there is mounted in a suitable recess formed inthe machine frame a spring pressed plunger 21 which. acts upon theshoulders 22, 23, respectively, when the guard support is placed inoperative or inoperative position, as indicated.

While it is desirable that the 14 shall be interposed between the looperand the work during the sewing operation, it is equally desirable attimes that the looper and adjacent mechanism disposed back of the guard1.4 be readily accessible, as well. understood by those familiar withthis class of machines, and the hinged mounting of the guard supportprovides means whereby the guard be readily turned into operative orinoperative position and held in either of said positions withoutfurther attention on the part of the operative.

What is claimed is 1. In a sole-sewing machine, the combination of thework support, the needle and looper, means for moving the looper aboutthe needle, a guard support mounted on the machine frame to be movedinto and out of operative position, and a guard sustained by saidsupport to protect the work from conflexible guard saunas in front ofthe looper to protect the work supported on the work support fromcontact by the looper as the latter carries the thread about the needle.

3.. In a sole-sewing machine, the combination of the work support, theneedle and looper, means for moving the looper about the needle, aguard, a guard support mounted upon the machine frame to swing the guardinto and out of operative position in front of the looper to protect thework supported on the work support from contact by the looper as thelatter carries the thread about the needle, and means for holding theguard in either operative or inoperative position.

4.. In a sole-sewing machine, the combination of the work support, theneedle and looper, a flexible guard disposed below the work support infront of the looper, a guard support hinged to the machine frame andcarrying said guard, a spring for holding the guard support and guard ineither operative or inoperative position, and a stop to limit themovement of the guard support and guard in one direction.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
